1 Claim.

This invention relates to a photo copy machine, with more particularreference to the type of apparatus in which drawings, documents and thelike are photographed on a sheet of sensitized 5 paper that travelsthrough the machine from a roll, the exposed portion being fed andsevered after each exposure, and it has for its object to afford simpleand eflicient mechanism for preventing twisting or skewing of the paper,or flexing of its edges, as it is fed through the machine.

A further object of the invention is to afford a mechanism that isreadily adjustable for cooperation with paper of different widths, andwhich can be set to engage the edges of the paper loirrespective ofitswidth and to prevent flexing of such edges as the paper travelsthrough the machine.

To. these and other ends, the invention consists in the construction andarrangement of parts that will appear from the following descriptionwhen read in conjunction with the accompanying drawings, the novelfeatures being pointed out in the claims following the specification.

In the drawings: Fig. 1 is a side view partially broken away andpartially in section, of a photo copy machine showing applied theretoone practical embodiment of the invention;

Fig. 2 is a vertical sectional view on the line 22 of Fig. 1, and

- Fig. 3 is a transverse sectional view on line 3--3 of Fig. 2.

This application is a division of original application filed July 19,1935, Serial No. 32,246, and referring more particularly to the drawingsin which like reference characters refer to the same parts throughoutthe several views, I designates a camera body, 2 is the usual bellows,and 3 is the magazine, while 4 is a roll box or sensitized papercontainer from which paper is threaded into the magazine 3, allsubstantially in accord with the structures disclosed in Patents Nos.1,992,492, W. P. Lloyd, February 26, 1935, and

1,998,324, W. P. Lloyd, April 16, 1935.

In order to prevent the paper curling or Warping away from the focalplane at its edges, a pair of vertical guides H are provided each ofwhich is L-shaped in cross-section, as shown in Fig. 3, to overlie theedge of the paper and also extend across the surface of the paper for aportion of gages a threaded portion its width. It will be understoodthat the guides ll cooperate with the edges of the paper strip from topto bottom of the focal plane, and they are adjustable uniformly in alateral direction so as to make possible proper cooperation with papersheets of different widths.

To accomplish this, each vertical guide II is provided with a nut l2 atits upper end that en- IS on the adjusting shaft M, the latter beingmounted in suitable hearings in the frame of the machine and having anoperating handle IE5 at its outer end. The guides II are supported onthe shaft I4, the portions I3 being threaded in opposite directions, andby turning the handle l5 and shaft I like-- wise, the guides II aremoved uniformly in opposite directions toward or from the center of thepaper strip so that they are brought into proper relationship with theedges of the paper, designated at l6, and which travels from the rollbox through a slot I! in the magazine and thence downwardly between thebacking plate of the magazine and the guides ll.

While the invention has been described with reference to the particularembodiment shown, it is not confined to the details disclosed, and thisapplication is intended to cover any modifications coming within thepurposes of the improve ment or the scope of the following claim.

We claim:

In a photo copy machine, the combination with a stationary backing platehaving a level surface against which paper is fed and having an openingthrough which the paper is introduced, of a pair of guides independentof the backing plate and extending endwise thereof, each of said guidesbeing L-shaped in cross-section with its short portion located adjacentto the edge of the paper and the edge of said short portion terminatingaway from the plane of the backing plate and its long portion locatedover and in close relation to the edge of the paper, said guidesextending above and below the aforesaid opening, and means cooperatingwith said guides at their upper ends beyond the aforesaid opening andoperable to adjust them simultaneously toward or from each other toaccommodate paper of different widths.
